I have fixed this by changing my xorg.conf file from this:
Section "Device"
Identifier "Default Device"
Option "NoLogo" "True"
EndSection
to this:
Section "Device"
Identifier "Default Device"
Option "NoLogo" "True"
EndSection
Section "Screen"
Identifier "Default Screen"
Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection
